Match the Terms with the Correct Definitions Question 1 options: linear momentum coefficient of restitution kinetic energy gravitational potential energy joule impulse 1. Ratio of the velocity of separation to the velocity of approach between two colliding 2. Energy due to the vertical position of an object; weight times height above some reference or mass times acceleration due to gravity times height above some reference; expressed as units of force times units of length or as joules in SI; a scalar quantity. 3. Average force times the duration of application of the force; causes and thus is equal to change in linear momentum; measured in units of force times units of time or expressed as newton seconds in SI; a vector quantity. 4. SI unit of measure for work and energy; equal to one newton meter. 1 J = 1 Nm. 5. Energy due to the motion of an object; half of the mass times the square of the velocity of the object; expressed as joules in SI; a scalar quantity. 6. Mass of an object times the linear velocity of the object; measured in units of mass times units of length divided by units of time or as kilogrammeters
